Submerged piles are often used as anchoring system in foundation of structures. They help to transfer the ground pressure acting on sheeting to the subsoil. They are mostly used in anchoring of the sheet piles, pile and underground walls into the surrounding soil massif. Other options of use are support walls and bank walls, under-washing protective walls, bank fortifications, swelling-up equipment in ship berths, etc. Anchoring system consists of drawing rod, fixed with its one ending to sheeting and with the oth...

Soil Swelling is a relatively complicated phenomenon not yet fully understood by researchers; however, it has been proved to be a physiochemical phenomenon related to soil and location. A tunnel support system can undergo failure upon completion of construction unless sufficient knowledge of expansive soil behavior is obtained and due procedures are followed to prevent the adverse effects thereof. This is a comprehensive study conducted on the physiochemical parameters affecting soil expansion, aimed at determinin...

The Kuznica Warezynska surface reservoir with an area of 5.6 km2 is located in the Silesian district, southern Poland. It was established in 2006 as a result of flooding of a sand pit after over 40 years of mine operation. Currently, it has various functions, the most important of which are flood control and recreational. The long-term dewatering of the pit and its subsequent flooding caused significant changes in the geochemical conditions in the Quaternary aquifer composed of sands and gravels. In addition, nume...

A significant part of geotechnical structures such as parts of tunnels, adits, retaining walls, etc., is made of reinforced concrete. In reinforced concrete structures there are often cracks in places where they were not considered in the design. It is up to the engineer performing the fault diagnosis to determine the nature of the cracks, the cause of the occurrence and the follow-up measures to prevent their further development or eventual sanitation. The principles of conventional methods of visual diagnosis of...

The theoretical analysis is based on the mathematical models of morphological patterns of the thermokarst plains and thermokarst plains with fluvial erosion in case of the ?synchronous start? of the thermokarst processes and little change of climate. The synchronous start means that the initial thermokarst depressions had appeared during a relatively short period and then only their size changed under thermos-abrasion or they disappeared due to their drainage by erosion streams (at the thermokarst plains with fluv...

Shallow mass movements represent a significant portion within the vast family of landslide phenomena. Moreover, their detection, monitoring and stability analysis is not an easy task. Analytical stability models are often used for the purpose. Their formulation ranges from extremely simple ones to rather complex formulations which include a number of physical parameters intrinsic to the terrain as well as external forcing agents. The application of such models seems to be strictly site-specific as various authors ...

This article presents a case of reclamation of excavations after exploitation of gravel located in the Vistula River near Oswiecim. Gravel deposits are located there shallowly below the surface and they are associated with river accumulation. This area is characterized by a very high level of groundwater vulnerability. After depletion of the gravel field, the excavations are liquidated by backfilling with waste, usually mine waste. The material to be used underwent a formal assessment of its impact on the aquatic ...

Statistics analyses confirm that the most common reason of dam failures and accidents is overflow and seepage. The issue of seepage is related to the reliability of the sealing elements in the body and the foundation of the dams. So far, 290 dams have been built in Slovakia, of which 50 are included in the ICOLD register. Most of them have a grout curtain in the foundation. Many of these dams were designed between 1950 and 1980. Lugeon or Jahde's water pressure test criterion was applied to optimize the parameters...

This article deals with the fire safety test of polymer sleepers in the ballasted track. Although the occurrence of a fire in the track is unlikely, it may occur, for example as a consequence rolling stock fire or arson. In the past, old rolling stock assembly or track maintenance could lead to fire. For these reasons, products installed in track must be fire-safe. A new trend in the sleeper development is the utilization of polymer-based materials that suitably combine the beneficial properties of prestressed con...

The history of mining using open-pit mining method indicates a trend of increase in depths of mining. At the beginning of the 20th century mining operations were carried out within sedimentary rocks and the maximum depth of pits of that time didn't exceed 100 m from a surface. However, several decades later the maximum depths of open-cast mine developments reached 200-300 m. Further growing demand for mineral raw materials caused an improvement of technique and technologies, the maximum depth of conducting open-ca...

The assessment of the vulnerability to pollution/contamination of natural mineral water is of maximum importance for long term exploitation of such a specific aquifer. A physically-based approach on the vulnerability should be based on three factors describing a pollution event, which are, the contaminant transfer time from the hazard location to the protected 'target', the level of contaminant concentration potentially reaching the 'target' and the contamination duration at the 'target' [1]. The main purpose of t...

The expansive soils, known for significantly volume changes when subjected to moisture, pose major problems to foundations, causing severe damages to structures built on this kind of soils. Recent environmental approaches are focused on the conservation of natural resources and on reducing the effects of waste landfills by recycling and reusing different types of waste materials. In this perspective, a sustainable way to deal with expansive clay soils is to integrate them back into secondary building materials or ...

The Upper-Pontian aquifer is one of the most important in Northwest Bulgaria. It is built of sands with a thickness of up to 100 m that outcrop on the surface at the periphery of the Lom depression. The aquiferous sands are overlain by a lignite coal layer up to several meters thick. In order to assess the influence of coal on the chemical composition of groundwater, an experiment has been carried out in laboratory. In view of the leading role of rainwater, the experiments were conducted with real rainwater. This ...

The Cieszyn Tufa Springs is a special area of conservation located in the Western Carpathians (southern Poland). The main subjects of protection are springs that outflow from the contact zone between Cretaceous limestones and slates. Due to a high vulnerability of shallow aquifers within the area of Cieszyn Foothills as well as urbanization and highly-developed industry of the Silesia region, a wide range of contaminants is detected in the spring water.

Kozhukhovskaya metro line is under construction in the southeast of Moscow now. The geological cross-section at the construction site shows Carboniferous limestone at a depth of 30-65 m, overlain by Jurassic and Quaternary clay, loam, sand and sandy loam. The principle geohazards originate from the presence of the thick horizon of water-saturated sandy and sandy-loamy deposits. These deposits serve as an enclosing medium for the future metro tunnel. The deposits along the route were typified according to their res...

Reinforced concrete tanks are currently used for storage of different substances and products. Such as bulk material but also various liquid and gaseous substances. Most often they serve as reservoirs for drinking water, for wastewater treatment and storage of various technical liquids. Rectangular tanks are less used as cylinders, but they have their advantages, less sensitivity to unilateral load, and better use of space for a multi-tank system. The rectangular tank solved in this article is filled with water. T...

Thermokarst plains with fluvial erosion were studied for the prognosis of their development including natural exogenous hazards. These plains develop through two contrasting processes: 1) thermokarst lakes appearing and increasing in size, 2) drainage of the lakes through fluvial erosion and their transformation into khasireis (drained thermokarst depressions). The present research deals with four different variants of development of the thermokarst plains with fluvial erosion. The research uses mathematical model...
